Abstract

Sanitary tissue products employing fibrous structures that exhibit a novel combination of compressibility properties, plate stiffness properties, and slip stick coefficient of friction properties, and methods for making same.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A sanitary tissue product roll comprising a multi-ply sanitary tissue product comprising a plurality of pulp fibers, wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 36 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method, a Plate Stiffness of less than 3.75 N*mm as measured according to the Plate Stiffness Test Method, and a Slip Stick Coefficient of Friction of less than 500 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method. 
     
     
       2. The sanitary tissue product roll according to  claim 1  wherein the pulp fibers comprise wood pulp fibers. 
     
     
       3. The sanitary tissue product roll according to  claim 1  wherein the pulp fibers comprise non-wood pulp fibers. 
     
     
       4. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product comprises an embossed fibrous structure ply. 
     
     
       5. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product comprises a 3D patterned fibrous structure ply. 
     
     
       6. The sanitary tissue product roll according to  claim 5  wherein the 3D patterned fibrous structure ply comprises a through-air-dried fibrous structure ply. 
     
     
       7. The sanitary tissue product roll according to  claim 5  wherein the 3D patterned fibrous structure ply comprises a fabric creped fibrous structure ply. 
     
     
       8. The sanitary tissue product roll according to  claim 5  wherein the 3D patterned fibrous structure ply comprises a belt creped fibrous structure ply. 
     
     
       9. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product comprises a conventional wet-pressed fibrous structure ply. 
     
     
       10. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 37 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method. 
     
     
       11. The sanitary tissue product roll according to  claim 10  wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 38 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method. 
     
     
       12. The sanitary tissue product roll according to  claim 11  wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 40 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method. 
     
     
       13. The sanitary tissue product roll according to  claim 12  wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 42 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method. 
     
     
       14. The sanitary tissue product roll according to  claim 13  wherein the multi-ply sanitary tissue product exhibits a Compressibility of greater than 46 mils/(log(g/in 2 )) as measured according to the Stack Compressibility Test Method. 
     
     
       15. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.6 N*mm as measured according to the Plate Stiffness Test Method. 
     
     
       16. The sanitary tissue product roll according to  claim 15  wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.5 N*mm as measured according to the Plate Stiffness Test Method. 
     
     
       17. The sanitary tissue product roll according to  claim 16  wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3.25 N*mm as measured according to the Plate Stiffness Test Method. 
     
     
       18. The sanitary tissue product roll according to  claim 17  wherein the multi-ply sanitary tissue product exhibits a Plate Stiffness of less than 3 N*mm as measured according to the Plate Stiffness Test Method. 
     
     
       19. The sanitary tissue product roll according to  claim 1  wherein the multi-ply sanitary tissue product exhibits a Slip Stick Coefficient of Friction of less than 450 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method. 
     
     
       20. The sanitary tissue product roll according to  claim 19  wherein the multi-ply sanitary tissue product exhibits a Slip Stick Coefficient of Friction of less than 400 (COF*10000) as measured according to the Slip Stick Coefficient of Friction Test Method.
